Is there any good excuse that SNMP client software can't handle a basic
design of SNMP - indexed tables?  ifIndex is far from the only index in
SNMP, and many of them still change today at various times.

It isn't that hard to fetch the indexed field in a bulk get, rewalking
the table if you don't get what you expected.  Cricket did this in 1999.
